An assembled insulation board connecting device

Abstract

The utility model discloses an assembled heat preservation board connecting device, the device is with the protection layer as the main part, and the heat preservation layer is inlaid in its inside to realize the heat preservation function. On the connecting structure, the top is provided with lower clamping piece and upper clamping piece, and the tapered head of upper clamping piece is inserted into the expansion strip gap of lower clamping piece, so that the expansion strip is expanded to realize the stable connection of upper and lower plates. The coupling of trapezoidal lug and trapezoidal recess and wedge-shaped lug and wedge-shaped recess provides the front and back and left and right direction limit for the protection layer, and enhances the overall stability. At the same time, the four corners of the front and back side walls of the protection layer are inlaid with sealing strips, and the sealing strips are in close contact during butt joint, so that the sealing property is improved, and air penetration is prevented. The device is simple in structure, convenient to operate, can effectively improve the connecting strength, sealing property and heat preservation performance of the heat preservation board, and is suitable for various heat preservation projects.
